I found that problem was too many continuous spaces between tags in
header part.
If amount of spaces was more than 1000, mod_proxy_html module wrongly
assumed that head part is finished, arbitrary closed head and opened
body without attributes (and then ignored original one).
As the most part of spaces is produced by colorThemeInit.vm foreach
loops, I replaced each pair of leading spaces with only one.
(Note that increasing ProxyHTMLBufSize didn't help.)

(see details in http://odo.lv/Recipes/XwikiShortURLs_en )
and strangely I can't do it for newer Xwiki instance
(it works for odo.lv which uses 2.7 version).
I found out that HTML is broken, when proxy server rewrites hyperlinks for preduced
XHTML
(SetOutputFilter proxy-html
ProxyHTMLURLMap /xwiki/bin/view/ /
direcives in apache2.conf)
Then it changes ...<body id="body" class="wiki-xwiki space-Main
viewbody
hideleft">... to simple ...<body>... element without attributes.
Only weakly related thing I found is that could be related is:
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxybadheader
I suspect it somehow is related on how header is
finished and body is started.
We have web standards validation tests that ensure the HTML produced
for the default wiki pages (at least) is valid, so I believe this is a
bug in the proxy filter. You can pass the HTML produced by your wiki
page to an XHTML validator like http://validator.w3.org/ to double
check.
Hope this helps,
